This invention has for its salient object to cut down the time'required for the functions above set forth and to provide. a machine constructed and arranged to efficiently and quickly perform saidfunctions.

Another object of the invention is to provide a machine of the character described that issimple and practical in construction, efficient in operation, and can be economically manufactured.

Further objects of the invention will appear from the following specification taken in connection with the drawings, which form a part of this application, and in which Fig. 1 is a vertical sectional elevation of a machine constructed in accordance with the invention, this view being taken substantially on line 1.1 of Fig.2

The invention briefly described consists of] a machine comprising means for feeding baking tins, means adapted to engage and clean the tins as they are fed, and means for greasing the tins after they have been cleaned. The tin feeding means is constructed and arranged to feed the tins con tinuously and the cleaning and greasing means are so coordinated in their movements with the feeding means that they will effectively engage the pockets in the tins and thoroughly clean and grease the pockets as the tins are fed.

Further details'of the invention will appear from the following description.

In the particular embodiment of the in- ;GREASING, MACHINE 1930. Serial No. 453,636.;

vention illustrated, the machine comprises side frames 10 and 11, each side frame. in

turn comprising upright frame members or pedestals 12 and 13- and a longltud nally extending connecting frame 14 The two side frames 10 and 11 are connect ed by cross slats 15 which support L-shaped guide rails 16 and 17, which in turn are adapted to receive and support the longitudinal side edges 18 of the baking, tins 20.. The tins are held in positionduring their feeding movement by two sets of disks 21 and 22. Each set of disks is carried by a shaft 23 mounted in arms 24: pivoted on fixed brackets 25 carried by the machine frame. The shafts 23 are engaged by springs 26. and

27 which tend to pull the shafts downwardlyf and 32. Each set of wheels, in the form of;

the invention illustrated, comprises three exactly similar feeding wheels and each wheel consists of a disk 35. having adjustably mounted thereon a plurality of peripherally extending lugs 36. In Fig. 4 the lugs are shown as secured to the disk by bolts 37 which are carried by the disk and extend through slots 38 in the lugs. The disks. are.

keyed to the shafts, as shown at 39; in Fig.3. V

The lugs 36 are so shaped andareso spaced as to extend into. the pockets or re-. ceptacles formed in the tins in the manner clearly shown in Fig. 1. The "brushing and cleaningmechanism comprises in the embodiment of the inven-j outer edges 18 tion shown, three sets ofbrushes adapted to" enter the three sets of pockets, or receptacles formed in the tins.

In Figs. 1 and 5"the cleaning-brushes: 44 are shown as extending radially with reference to a'shaft 45, the brushes being carried bythe shafts 46 rotatably mounted in journal bosses 47 formed in a'casing or drum 18. Each shaft" 46 has abevelgear. 49 on its inner end which meshes with a bevel gear 50 mounted to rotate with the shaft 45.

The main power or drive shaft for the machine is shown at in Fig. 1 and is driven from any suitable source of power. The shaft 55 has mounted thereon a worm 56 which meshes with a worm gear 57 carried by a shaft 58. sprocket wheel 59 secured thereto, driven by the worm gear 57 and connected by a sprocket chain 60 to drive a sprocket wheel 61 which is fixed to the shaft 45. Three bevel gears 50 are mounted on and driven by shaft 45, one for each set of brushes.

The casing or drum 48 is rotatably mounted on the shaft 45 and has connected thereto a worm wheel 70 which is driven by a worm 71 mounted on the shaft 55. A sprocket wheel 75 is also rotatable with the drum 48 and worm wheel 70. Wheel 7 5 is connected by a chain 76 to drive a sprocket wheel 77 mounted on the shaft 32 of the feed wheels ,and by means of their rapid rotation there 35" in. thoroughly remove from the pockets all extraneous matter therein left over from a previous use of the tins.

After the tins have been cleaned by the rushes 44 they are greased in the manner which will now be described. In Fig. 2 there is shown three sets of bosses 80, 81 and 82 which are carried by acasing or drum 83 rotatably mounted on a fixed shaft 84.

.The casing or drum 83 is connected to and 45 driven by a worm gear 86 and worm 87 from the shaft 55. Each of the sets of bosses 80, 81 and 82 carries a plurality of radially extending shafts 88, on the outer ends of ,which are mounted brushes 89. The three sets of brush shafts 88 have secured to the inner end thereof, bevel gears 90, 91 and 92 which mesh with bevel gears 93, 94 and 95 fixed on the shaft 84. The gear 94 faces in a direction opposite to the gears 93 and l 95 and the center set of brushes will, there'- fore, rotate in a'direction opposite to the direction of rotation. of the other two sets of brushes.

The drum 83 is thus driven from the shaft 55 by means of the worm and worm gear connection 87, 86 to rotate the disks 80, 81 and 82 and as the casing or drum 83 is rotated the brushes 89 carried thereby are m driven by means of the bevel gear coina tions described since the gears 93, 94 and 95 The shaft 58 has a are stationary. Should the bristles on the two outer sets of brushes be laid over or flattened by use, they can be transferred to the center set, whereupon the opposite rotacarried by the shafts 30 and 31.

The grease for greasing the tins is first applied to the brushes 89 and is applied by the brushes to the tins. The brushes 89 receive thegrease from oppositely facing conical disks 110 carried by the shaft 111. This shaft has mounted thereon a gear 112 which meshes with a gear 113 mounted on jack shaft 114 on which is alsomounted a sprocket wheel 115. The wheel 115 is driven by a chain 116 from the sprocket wheel 117 carried by the shaft 30.

The disks 110 rotate in a receptacle 120 having grease therein and, as shown in Fig. 1, dip into the grease during a portion of their rotation. As the brushes 89 pass between the oppositely facing conical disks and rotate in contact therewith, they receive grease from the disks, and during their rotation in the pockets or receptacles formed in the tin, the brushes transfer the grease to the tin. Attention is called to the fact that the brushes 89 rotate at a much slower rate of speed on their axes than do the brushes 45 which clean the tins.

The rate of rotation of the brush drums or casings 48 and 83 and the arrangement of the sets of brushes radially on these shafts are so worked out that the brushes will enter the pockets, perform their functions, and leave the pockets during the feeding movement of the tins by the tin feeding mechanisms A, B and O. Furthermore, the brushes 89 are so driven as to receive and deposit on the tins a relatively thin film of grease. 1

From the foregoing description it will be seen that the machine described will operate continuously without attention to thoroughly and efficiently clean and grease baking tins of the type specified. It will be understood that as many sets of cleaning and greasing brushes may be provided as are necessary to clean and grease all of the pockets or receptacles formed in the tins.

Although one specific embodiment of the invention has been particularly shown and described, it will be understood that the invention is capable of modification and that changes in the construction and in the arrangement of the various cooperating parts may be made without departing from the spirit or scope of the invention, as expressed in the following claims.
